Our take

Fraud is a multi-billion dollar problem for the eCommerce industry, and one that Ravelin is tackling head-on. The company develops machine learning-based technology to help online merchants and payment service providers reduce losses to fraud, and improve the acceptance rates of orders.

Ravelin aims to give merchants more confidence in accepting customers and transactions, while tackling organised fraud rings. The value of such an offering is clear, which is how the company has secured enterprise customers like Just Eat and Quiqup.

A 2022 partnership with Mastercard enabled Ravelin to enhance its platform with digital identity verification capabilities and real-time fraud insights. In 2025, it was acquired by Worldpay as part of its strategy to accelerate its eCommerce growth through investing in innovation and AI technology.
